Consider defining a bean of type `xxx` in your configuration问题解决

在使用SpringBoot装配mybatis时出现了异常

***************************
APPLICATION FAILED TO START
***************************

Description:

Field studentService in com.example.demo.action.StudentController required a bean of type 'com.example.demo.service.StudentService' that could not be found.

The injection point has the following annotations:
	- @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'com.example.demo.service.StudentService' in your configuration.


Process finished with exit code 0

public class SpringBootApplication {
